Session 13: Practice 4
- Time: 2h
- Date: Wednesday, March-11th-2020
- Goals: *
The goal of this practice is to develop a web server with information about the four bases: A, C, T and G. Each base should have its page, with the following information: Name, letter, chemical formula and a link to the wikipedia URL with more information. In addition, each page will be in a different color. This table describe the names of the resources (path) for getting the web pages
| Resource | html page | Description |
|---|---|---|
| /info/A | A.html | Information about the Adenine base. Color: lightgreen |
| /info/C | C.html | Information about the Cytosine base. Color: yellow |
| /info/G | G.html | Information about the Guanine base. Color: ligthblue |
| /info/T | T.html | Information about the Guanine base. Color: pink |
We will implement the Web Server step by step. The exercise will guide you
- Filename: P4/A.html
Let's start by writing the HTML page for the Adenine base. We will use it as a template. The pages for the other bases will be similar but with a different color and information
The page should look like this:
You can preview your page with pycham. Just open the html file in pycharm and press on the top right brower icons. For example in firefox's icon:
The page is quite similar to the Page of the Green server. Use the H1 tags for the base name, and the P tags for the letter and its chemical formula. Finally, you can place links to other URLS using the a tag. In this example you can see how to place a link to the wikipedia's main page:
<a href="https://en.wikipedia.org/">Wikipedia</a>- Filename: P4/EX2.py
- Description: Write a webserver that returns the A.html file when the info/A resource is requested by the client. When the URL http://127.0.0.1:8080/info/A is written in the browser, we should see the web page of the A base. If another resource is requested, the server will send a response message with a blank body (therefore a blank page will be shown)
- Filenames: P4/C.html and P4/EX3.py
- Description: Extend the previous web server for accessing to the web pages of the C base, in addition to the A base. It should be available in the path /info/C
- Filenames: P4/T.html and P4/EX4.py
- Description: Extend the previous web server for accessing to the web pages of the G and T bases, in addition to A and C. They should be available in the path /info/G and /info/T respectively
- Filename: P3/Seq-Server.py
Modify the Seq server for implementing the REV command. The client sends a message with the word REV followed by a sequence. The server will return a response message with the reverse of the given sequence. It should be obtained using the Seq Class
For testing the server we use commands like this, executed from the Linux's command line:
printf "REV AACCGTA" | nc 127.0.0.1 8080
This is what is shown in the Linux's console:
And this is what we should get in the Server's console:
- Filename: P3/Seq-Server.py
Modify the Seq server for implementing the GENE command. The client sends a message with the word REV followed by a gene name: U5, ADA, FRAT1, FXN or RNU6_269P. The server will return a response message with the complete sequence of that gene. It should be obtained using the Seq Class (and reading the gene from the corresponding file)
For testing the server we use commands like this, executed from the Linux's command line:
printf "GENE U5" | nc 127.0.0.1 8080
This is what is shown in the Linux's console:
And this is what we should get in the Server's console:
- Filename: P3/test-client.py
Finally let's create a client for testing our server. You should use the Client class from practice 2. Use the talk method
For the services INFO, COMP and REV, use the sequence obtained when calling the GET 0 command
The client should write messages on the console indicating the test it is performing and the response obtained from the server:
